Accuracy Evaluation Method of Disparity after Style Transfer in Stereo Image

Abstract

One of the simplest way to realize a stereoscopic style transfer is using monocular style transfer to stereo image as normal still image. However, deformation caused by style transfer deteriorates the disparity information of stereo image, so improvement of style transfer needs a evaluation method for transferred image. In this paper, evaluation image of disparity information for stereoscopic style transfer of stereo image and its numerical evaluation method are proposed. Proposed evaluation image determines three regions from transferred image, they are ”correct disparity region, loss of disparity region, incorrect disparity”. And numerical evaluation in each region employs their area whose value is normalized. In an evaluation experiment, parameter of evaluation image is considered, and the basic property of the them are showed. Finally, its effectiveness for stereoscopic style transfer is also showed by using pencil art generation method.
